A pumping port provides a tie-in to the force main in case there is a problem with the lift station that causes the wet well to fill to capacity. This allows for an emergency mobile pumping system to drop in to the wet well and pump the inflow to the existing force main. The pumping port is located downstream of the check valve in either a valve vault or a separate enclosure. The check valve prevents the water from reentering the wet well. This method is an affordable way to prevent overflow in emergency scenarios; otherwise, the inflow would need to be pumped to trucks and hauled to a discharge point or treatment. Romtec Utilities always suggests designing a pumping port into a lift station package.
